SHORT TERM (Tonight through Friday Night). Afternoon surface analysis shows a cold front sliding out of northwest Texas into the Big Country. Warm air advection east of the Highway 183 corridor continues to produce light, isolated showers this afternoon across the Coastal Plains with a secondary area of shower and isolated thunderstorm development noted across Central Texas as an upper level speed maxima noses overhead. Slow forward movement of the front is expected through the overnight hours as the front remains oriented roughly parallel to southwest flow aloft. The potential for showers and isolated thunderstorms will continue into the evening hours across the Hill Country and Central Texas in the vicinity of the aforementioned jet streak.

Veering mid and upper level flow as a closed low near the Four Corners this afternoon slides into the Central Plains on Friday will nudge the cold front across the region after sunrise Friday. A thin band of showers developing along the cold front may be preceded by an early to mid morning round of showers and isolated thunderstorms closer to the Interstate 10/Highway 90 corridor as a secondary, weaker upper jet streak slides across South Central Texas from Mexico. Expect the front to push south of the region Friday afternoon with rain chances shifting south and east with it. Drier and cooler conditions are expected behind the front with morning temperatures in the low to mid 60s remaining steady or falling during the afternoon in the Hill Country and Central Texas behind the front. Portions of the Rio Grande Plains are still expected to reach the mid 70s tomorrow afternoon before frontal passage. Dry and cool conditions will settle in Friday night with lows in the upper 30s to mid 40s north of the Interstate 10/Highway 90 corridor and upper 40s to low 50s south.

LONG TERM (Saturday through Thursday). A trailing trough axis associated with the Central Plains low clears region during day Saturday, resulting in dry northwest flow aloft through Monday. This will keep dry, clear, and mild conditions in place during this time with highs this weekend in the upper 60s to mid 70s this weekend warming into the mid 70s to low 80s by Monday. A shortwave trough lifting into the Southern Plains early next week as a longwave trough amplifies along the West Coast will send a cold front into the region on Tuesday. Limited Gulf moisture return ahead of the front will keep rain chances fairly minimal mid-week, but the front lifts back north as a warm front by Thanksgiving and have maintained low rain chances heading into the holiday as the West Coast trough begins swing eastward.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
